The big question is how the table gets populated with the data and enables things like column based sorting all executed on the client side. (With the associated interactions with scrolling). The point of recycling views is as row UI elements scroll off the top they are reused for those appearing at the bottom (or vice versa) which reduces system resources for these things a lot. This way the data table can contain 20 million rows but if the user can only see 100 the UI only pays the cost for 100. This is standard practice in native app dev and I think is a good example for the case they are making. I would argue such a thing would be needed in the hypothetical NeXT type API of course.
